Specification of Letters Patent.

Application filed November 19, 1914. Serial No. 872,998.

To all whom it may concern.

Be it known that I, MALCOLM GORDON, a citizen of the United States of America, residing at Lisburn, county Antrim, Ireland, have invented certain new and useful Improvements in and Relating to Yarn VVinding, Twisting, and Doubling Machines, of which the following is a specification.

This invention has reference to automatic stop motions of the detector box type for use in connection with yarn winding, twisting and doubling machinery, and relates more particularly to an auxiliary attachment forming a combined yarn clearer and slub or lump detector which is adapted to be supplied to, and act in conjunction with, stop motions of this type, for the purpose of increasing the utility thereof.

Heretofore stop motions have been caused to act by. the breaking or running out of the yarn. I

Under the present invention the attach ment forming the slub or lump detector is so constructed and arran ed that when, during the onward travel 0' the yarn, a lump,

7 or slub, or knot, contacts with a movable part thereof it will cause that part to be moved and so operate means as to cause the stop motion to come into action automatically and stop the'travel of the yarn without breaking same, whereupon the worker or attendant may remove the slub or lump. 7

The movable part or detector proper is suitably supported and is adapted to be moved against the action of a pendulum,

- weight, spring, or like means, and the passage for the yarn through or past the same is such that, while the movement of the detector stops the machine, it also releases the slub or lump without breaking the yarn, so that there is a considerable saving resulting from the avoidance of waste yarn.

In order that my invention may be clearly understood I have hereunto appended explanatory sheets of drawings whereon it is shown in some of its forms by way 'of example or illustration.

Figures 1 and 2 are respectively elevation and plan views of a slub detector in accordance with my invention as applied to a with my invention as applied to a twisting frame having a stop motion of the box detector type.

On the drawings the same reference letters wherever repeated indicate the same or similar parts. I

Referring to the drawings :In carrying out my invention as applied to a doubling frame and as shown at F igs. 1 to 3, I provide in addition to the usual detector drop pins a, one or more additional drop pins. In the example shown an additional drop pin Z) is provided. The extra drop pin 5 is suspended by a cord 6 having one end 5 suitably supported at Z2 its other end 5* being attached to the detector plate 0? at 6 (see also Fig. 3.) The detector plate OZ is supported by and swings about a pivot d and it is normally held vertical by the action of the suspended weight or pendulum (Z which also puts sufficient tension on the cord 5 to keep it normally taut, but on the detector or plate (1 being struck by a slub or knot in the yarn it can be freely oscillated thereby so that the cord 6 is slackened and the pin Z) drops into engagement with the stop motion ratchet 6 thereby bringing the ordinary stop motion into action. When struck by a slub or knot as above described the detector plate (Z is immediately oscillated and at the same time its oscillation allows the slub or knot to pass onward without breaking the yarn and as the stop motion is immediately brought into action the operator can then remove the slub or knot and re-start the machine. As shown in Fig. 3 the detector plate d may be made with upwardly tapering slots or slits for different counts of yarn and thicknesses of slubs or lumps to be cleared. Instead of using a detector plate cl with suspended weight 05 as shown in Figs. 1 to 3, I may,

if desired, use a slitless plate 7 (see Fig.

I) suspended below the pendulum f on the pivot f the [plate f etc. being suspended over andadjustably supported with respect to a plate or bar g,'the yarn passing between the upper surface of the bar 9 and the lower edge of the plate f and so that any predetermined size of lump or knot will oscillate the plate 7' and cause it to operate the stop motion in themanner hereinbefore described while the lump passes on andclears the detector plate f without breaking the yarn.

In Figs. 1 and 2,there is an additional drop 'pin 0 suspended by a cord it having its one'end k attached to a fixed support if while its other end passes through an eye and issecured to one arm 2' of a bell crank lever 2', the other arm z' of which has an adjustable finger or pro ection '5 O n the completion of the winding of a cop or vbobbin a bar' Z suit ably pivoted, is moved to position to engage with and move'the fin- 41 which is supported at its one end n on a fixed support 11, while its other end is secured to an arm 0 of a bell crank lever 0 whose other' arm 0 is adapted to be" acted on by the'end p of a'weighted lever 79 on the roller axis 9. c I lever p has an eyep? through which the yarn passes and, in the event of its breaking, the end p of the lever falls therebyraising the endp which moves the lever 0 so that the cord n is slackened, and the pin m then engages and actuates the stop motion. The lever 0' normally tensions the cord n so as to keep the pin in clear ofthe stop motion. I

In certain cases the yarn may, after pass- ;ing the-detector above described, be guided by a porcelain guideor the like 8 and thence through an eye i (see Fig. 1).i

The distinctive improvement of the lump stop mot-ion attachment as described is that the onward travel of the yarn isstopped without the yarn being broken whereas with the old type of stationary detectors, when the slubor lump struck the detector the yarn was generally broken at the weakest spot with theres'ult that a considerable portion of yarn had to be pulled back entailing delay and also more waste than necessary in cutting out the lump.

Having now fully described my invention what I claim and desire to secureby Letters Patent is V 1.
